Setup New Rails Project

1. Create a new project with: >rails name_of_project, then: >cd name_of_project
2. Optionally if using other database than Sqlite: > rake db:create:all
3. Install RSpec Plugin & Framework. Refer to the latest instructions.
4. Run the RSpec generator to create framework: >ruby script/generate rspec
5. Create latest plugin documents on local drive with: rake doc:plugins. Location of documentation is "name_of_project/doc/plugins/respec-rails/index.html. Open directly in browser with: open -a Firefox doc/plugins/rspec_on_rails/index.html. Or open index.html
6. Install and run RSpec plugin framework if needed
   
7. Create the git repository with a cd to the "name_of_project" directory and then:

>git config --global user.name "your name"

>git config --global user.email "your mail@provider"

>git config --global apply.whitespace nowarn

to check the settings see .gitconfig or: >git config --list

>git init (creates local repository and the .git directory)

create a .gitignore file and add file to ignore

*.log

database.yml

db/schema.*

.DS_Store

>git add . (add all file and contents to firstime checkin)

>git commit -m "first commit"

>git status (check the repos)

Setup Rails 2.1 on Mac Leopard

A version of rails and gem is already installed on the mac so we will update and expand on this installation as follows

1. Get and Install TextMate
   
2. Get and Download MacPorts - Leopard (universal). After the download and installation, edit or add to .bash_profile file the following: export PATH="/opt/local/bin:/opt/local/sbin:$PATH" (see here for more details)
3. Update macports from the command line terminal with: >sudo port selfupdate. NOTE: I had a problem with awk not being found during the installation. This was solved by running the installation again.
4. Install Git and Svn integration as follows: >sudo port install git-core +doc +svn
5. Update gems with: >sudo gem update
6. Install Rspec gem with: > sudo gem install rspec
7. Install Zentest with: >sudi gem install ZenTest. You don't need to install the gem if you are only using rails. Zentest enables autotesting in the background.
8. Install Rspec TextMate bundle specifically for rails supporting development: cd to the TextMate Bundles directory, i.e. > cd ~/Library/Appliction\Support/TextMate/Bundles. Then: > git git clone git://github.com/dchelimsky/rspec-tmbundle.git RSpec.tmbundle
